[0025] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1 , Figure 2 A high-safety reinforced steel truss floor deck reinforcement structure includes a bottom steel plate 1. Multiple supporting channel steels 6 are welded to the outer surface of the bottom steel plate 1. These supporting channel steels 6 are distributed in parallel, and their cross-sections are U-shaped. Multiple sets of through holes are provided on the outer surface of the supporting channel steels 6. Each set of through holes contains two steel bars, and two first reinforcing bars 5 penetrate through each set of through holes. The first reinforcing bars 5 are distributed perpendicularly to the supporting channel steels 6. Multiple connecting steel bar frames 4 are welded to the outer surface of the bottom steel plate 1. The connecting steel bar frames 4 are alternately distributed with the supporting channel steels 6. The multiple connecting steel bar frames 4 located on the same straight line are clamped between two first reinforcing bars 5 penetrating through the through holes on the outer surface of the supporting channel steels 6. The top of the connecting steel bar frame 4 is... Another first reinforcing bar 5 runs through the bottom steel plate 1 and is welded to the connecting reinforcing bar frame 4. Multiple parallel supporting channel steels 6 are welded to the outer surface of the bottom steel plate 1. The supporting channel steels 6 are perpendicular to the first reinforcing bar 5. This improves the structural strength of the prefabricated steel truss floor slab, thereby enhancing the stability and safety of the laying process. Furthermore, since some of the first reinforcing bars 5 pass through the through holes on the outer surface of the supporting channel steels 6, the connection area between the bottom steel plate 1 and the reinforcing bar frame is effectively increased, thus improving the connection strength between the bottom steel plate 1 and the reinforcing bar frame. This effectively improves the stability during concrete pouring, preventing large-area subsidence caused by the detachment of the steel plate from the reinforcing bar frame, and further enhancing safety performance.

[0027] Reference Figure 1Figure 2 shows that multiple connecting frames 7 are welded to the upper surface of the bottom steel plate 1. Each end of the connecting frame 7 has an insertion hole, and a second reinforcing bar 8 is inserted into the insertion hole. The second reinforcing bar 8 is distributed parallel to the supporting channel steel 6. A steel pipe sleeve 9 is sleeved on the outside of one end of the second reinforcing bar 8. By setting up the connecting frame 7 and the second reinforcing bar 8, and by sliding the steel pipe sleeve 9 on one end of the second reinforcing bar 8, the steel pipe sleeve 9 can be moved to connect the second reinforcing bars 8 at corresponding positions on the two adjacent bearing plates when splicing them. This allows for connection operations on adjacent bearing plates during the laying stage, effectively improving the stability of the connection and facilitating the subsequent construction of the reinforcing steel frame.

[0028] Reference Figure 1 , Figure 2 , Figure 3 The bottom steel plate 1 has a first connecting groove 2 and a second connecting groove 3 integrally connected to the symmetrical two sides. The first connecting groove 2 and the second connecting groove 3 cooperate with each other, which can effectively improve the sealing of the joint between two adjacent bottom steel plates 1 and prevent leakage during concrete pouring.

[0029] Working principle: During use, the initial prefabricated components of the steel truss floor deck are first erected at the designated location. During the laying process, the first connecting groove 2 and the second connecting groove 3 on the two adjacent bottom steel plates 1 are overlapped. Then, the steel pipe sleeve 9 is moved to connect the second reinforcing bars 8 at corresponding positions on the two adjacent decks end to end. Next, the steel pipe sleeve 9 and the second reinforcing bars 8 are fixed by electric welding. At this point, the laying is completed, and subsequent reinforcing bar insertion can be carried out. Since multiple parallel supporting channel steels 6 are welded to the outer surface of the bottom steel plate 1, and the supporting channel steels 6 are perpendicular to the first reinforcing bars 5, the structural strength of the steel truss floor deck in the prefabricated state can be improved, thereby improving the stability and safety of the laying stage. Furthermore, since some of the first reinforcing bars 5 pass through the through holes on the outer surface of the supporting channel steel 6, the connection area between the bottom steel plate 1 and the reinforcing frame can be effectively increased, thereby improving the connection firmness between the bottom steel plate 1 and the reinforcing frame. This can effectively improve the stability during concrete pouring and prevent the steel plate from detaching from the reinforcing frame, which could cause large-area subsidence.

Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
